Data visualization and decision-making are critical aspects of infrastructure inspections. Numerous research efforts have been made to develop practical remote inspection systems that overcome the limitations of conventional inspection methods. Although the integration of Immersive Virtual Reality (IVR) into remote inspection is currently being addressed, most IVR frameworks have focused on data accuracy and there has been a lack of research on developing human-centered IVR frameworks through usability evaluation. This paper addresses this limitation by proposing a new IVR development framework utilizing agile User Experience (UX) design techniques, which can be implemented in remote infrastructure inspections for data visualization and decision-making. Usability tests were conducted through a case study with 22 participants, using an IVR prototype developed in accordance with this framework. Following its implementation, the framework demonstrated its ability to identify damage via remote bridge inspection and achieved acceptable usability. Future research can build on the framework for semantic enrichment tasks. [ABSTRACT FROM AUTHOR]

• The hierarchical expression of conflict is applied to accurately identify conflict. • Agility attribute is involved in the calculation of the conflict solution tendency. • Ant colony optimization is applied to identify the multi-conflicts solution path. • The scientific and effectiveness of the method are verified by a case. An agile solution strategy is proposed to solve the multi-conflicts problem and low efficiency in the innovation process of product development. A hierarchical representation of the conflicts is formed using a layered conflict resolution diagram based on the current reality tree (CRT) for the problem identification. The conflict solution tendency is searched using a conflict solution tendency network (CSTN). An ant colony optimization algorithm is introduced to analyze the CSTN model for the global optimal solution. The multi-conflict agile solution path is obtained based on the mutually exclusive relationship between conflicts. The TRIZ tool is used to search the agile solution of the multi-conflicts problem. A case study of the innovative design of the multi-functional nursing bed verifies the proposed method. [ABSTRACT FROM AUTHOR]
